ELECTRIC LAMP HOLDER v Filed Feb. 19, 1955 INVENTOR Patented Oct. 29,1935 UNITED STATES PATENT OFFICE Elliott Clemence, Millburn, N. r.Application February 19, 1935, Serial No. 1,211

8 Claims.

This invention relates to a holder or support that is especially adaptedfor supporting the individual lamps of a string of Christmas tree lampsupon the limbs of trees or the like.

In carrying out the invention a resilient support is attached to thehusk of each lamp in such a way that the support is very rigidly andsecurely attached to the husk. The supports are adapted for attachingthe lamp to limbs or other objects of diflerent sizes and will hold thelamps in upright or other positions on the limbs as desired.

The invention will be understood from the description in connection withthe accompanying drawing in which Fig. 1 is a side view.of anillustrative embodiment of the invention Fig. 2 is a similar view takenat-rlght angles to Fig. 1; Fig. 3 is a plan view looking at the lowerend of the device and Fig. 4 is a side view of a modification oi thesupporting member.

In the drawing-reference character I indicates a husk for an. electriclight socket, this husk being made of insulating material, such, forexample, as phenol-formaldehyde condensation product, well known asbakelite. The husk I is approximately cylindrical in shape, but tapersslightly in a downward direction. It is open at its upper end I toreceive a lamp bulb and contains a screw shell and center contact (notshown) of the well known sort for receiving and making electricalconnection to the lamp bulb. The center contact and screw shell are inturn connected to contacts at the bottomof the husk I, to which contactsopposite wires 8 and 4 of line wires may be soldered after stripping oilthe insulation 6 for short distances along the wires. The cap I isforced on to the lower reduced end of the husk I to aid in keeping thewires 8 and 4 in place, slots 8 being provided on opposite sides of theflange oi the cap I for this purpose. The parts thus far described areold and well known.

The enlarged lug or extension I II is provided on the outside of thehusk I near its open end. A longitudinally extending slot II is providedin the lug It with its lower end open and its upper end closed. Thebottom of the slot I I is substantially flush with the outside surfaceof the husk I and the sides of this slot are dove-tail shaped with thewider part nearest the surface of the liusk, as most clearly shown inFig. 3. 1

YA clip or holder I2 has a central fastening extension I 8 which isinserted into the slot II from the lower open end. Teeth I4 are providedon opposite edges of the extension I8. These teeth slope downwardly andthe extension I3 is of such 9, width that the teeth I4 cut grooves alongthe sides of the slot II. As the holder is forced into place from belowinto the slot II It will be securely retained in place due tolthe factthat any attempt to withdraw the holder in the other direc- 8 tioncauses the ends of the sloping teeth I4 to dig into the sides of theslot II and prevent withdrawal. The dove-tail shaped edges of this slotprevent withdrawal perpendicularly to the husk.

Acircumferentially extending portion I of the holder I2 lies snuglyagainst the outside surface of the husk I. Arms I6 01' the holder I2extend at right angles to the portion I! from the ends thereof and alsorest against the husk I. Goose neck bends I? are provided at the upperends of is the arms I8, and spring arms I8 extend from the goose neckbends I1 and are preferably made of zig-zag or angular shape in alongitudinal direction. An integral extension It extends from the cen-2o ter .of the lower edge of the portion ii of the 'holder I2 parallelto the axis of the husk and therefore diverges slightly therefrom, asshown in Fig. 2. The end of the extension I 9 may be bent inwardly underthe end of the husk.

With a row of lights, such as Christmas tree lights, for example,connected to a pair of wires in the usual way, the individual lights canbe attached to limbs of different sizes simply by hooking the arms I8over the limbs and exerting slight pressure, whereupon the limb willenter between the arms I8 and the extensions I9 the proper distance tocause the lamps to be held in whatever positions they are placed.

The holder 2| shown in Fig. 4 has a toothed 85 fastening extension 22corresponding to the extension I3 in the other figures. A single springarm or clip 23 is connected to the extension 22 by means of a gradual orgoose neck bend 24 so as to avoid the danger of the same being broken byfiexure. A reverse bend 25 is provided near the end of the arm 23 toenable the lights to be readily fastened upon or hooked over a limb of atree in an upside-down position when desired. while retaining thepossibility of hanging the 4 lights upon limbs in upright positions withthe limb between the portions 28 and the husk to which the holder isattached.

I claim:

1. In an electriclight holder, -a husk of insulating material, anintegral lug along one side thereof having a slot with an open sidetherein substantially parallel to the axis of said husk and a supporthaving an extension frictionally secured in said slot.

121 11; an electric light holder, a husk oi. in- 'sulating material, anintegral lug along one side thereof having a slot therein substantiallyparallel to the axis oi said husk anda support having an extensionfrictionally secured in said slot, said extension having teeth engagingthe side walls oi said slot.

3. In an electric light holder, a husk 01' insulating material, anintegral lug along one side thereof having a dove-tail slot thereinsubstantially parallel to the axis of said husk and a support having] anextension projectinginto said slot and secured therein by friction;

4. In an electric light holder, 8. husk of insulating material, anintegral lug along one sidethereof having a slot therein substantiallyparal-.

lel to the axis of said husk and a support having an extensionirictionally secured in said slot, said support being provided with aspring arm.

theredi; having a' slot therein substantially parallel-to the axis ofsaid husk and asupport having an extension frictionally secured in saidslot, said support being provided with a pair oi. spring arms onopposite sides of said extension.
